1.使用nuget下載：.

Microsoft.Extensions.Configuration.Json

Pomelo.EntityFrameworkCore.MySql

2:建立實體類: 

GirlInfo

    public class GirlInfo
    {
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        [Column("id")]
        public int id { get; set; }
        
        [Column(
 
"title")]
        public string Name { get; set; }
        [Column("src")]
        public string Src { get; set; }


    }

3:配置連線資訊:

 public class EFCoreContext : DbContext
    {
       
        private string ConnectionString = "Server=localhost;Database=girl2;charset=utf8;uid=root;pwd=root;";
        
 
public EFCoreContext()
        {
               
        }
        public EFCoreContext(string connet)
        {
            DBConnectStr = connet;
        }
        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {

            optionsBuilder.UseMySql(ConnectionString,         ServerVersion.AutoDetect(ConnectionString), 
 
null);
        }
        public DbSet<GirlInfo> girlInfo { set; get; }
    }

4:使用ef的框架生成資料表:

add-migration q

update-database

5:大功告成.
